Tree Selection for Windbreak WindbreaksWindbreaks TheirTheir UseUse Morris J Houck USDA-NRCS Knox City Plant Materials Center IntroductionIntroduction z The difficulties in growing trees and shrubs where natural rainfall and other conditions are not the most favorable for tree growth should only stimulate the desire to succeed in planting and improving the home. The early ranchmen were not long in realizing the importance and value of tree planting and many of the old ranch headquarters are among the best planted home sites to be found, these early pioneers having taken advantage of the protection, comforts, and pleasures of trees.

  • EVERGREEN TREES for NEBRASKA Justin Evertson & Bob Henrickson
    THE NEBRASKA STATEWIDE ARBORETUM PRESENTS EVERGREEN TREES FOR NEBRASKA Justin Evertson & Bob Henrickson. For more plant information, visit plantnebraska.org or retreenbraska.unl.edu Throughout much of the Great Plains, just a handful of species make up the majority of evergreens being planted. This makes them extremely vulnerable to challenges brought on by insects, extremes of weather, and diseases. Utilizing a variety of evergreen species results in a more diverse and resilient landscape that is more likely to survive whatever challenges come along. Geographic Adaptability: An E indicates plants suitable primarily to the Eastern half of the state while a W indicates plants that prefer the more arid environment of western Nebraska. All others are considered to be adaptable to most of Nebraska. Size Range: Expected average mature height x spread for Nebraska. Common & Proven Evergreen Trees 1. Arborvitae, Eastern ‐ Thuja occidentalis (E; narrow habit; vertically layered foliage; can be prone to ice storm damage; 20‐25’x 5‐15’; cultivars include ‘Techny’ and ‘Hetz Wintergreen’) 2. Arborvitae, Western ‐ Thuja plicata (E; similar to eastern Arborvitae but not as hardy; 25‐40’x 10‐20; ‘Green Giant’ is a common, fast growing hybrid growing to 60’ tall) 3. Douglasfir (Rocky Mountain) ‐ Pseudotsuga menziesii var. glauca (soft blue‐green needles; cones have distinctive turkey‐foot bract; graceful habit; avoid open sites; 50’x 30’) 4. Fir, Balsam ‐ Abies balsamea (E; narrow habit; balsam fragrance; avoid open, windswept sites; 45’x 20’) 5.

  • Identification of Conifer Trees in Iowa This Publication Is Designed to Help Identify the Most Common Trees Found in Iowa
    Identification of Conifer Trees in Iowa This publication is designed to help identify the most common trees found in Iowa. It is based on vegetative characteristics including leaves, fruit, and bark. It is neither complete nor without possible oversights. Separate species are grouped by similar characteristics, mainly based on type and arrangement of leaves. These groups are; awl- or scale- like needles; single needles, flattened with rounded tips; single needles, square in cross section, with pointed tips; and needles in bundles or fasticles of two or more. Remember, vegetative character- istics are quite variable; use more than one specimen for comparison. Awl- or scale-like needles Juniperus Virginiana Eastern Red Cedar Leaves are dark green; leaves are both awl- and scale-like; cone is dark blue and berry-like. Thuja occidentalis Northern White Cedar Leaves are flattened and only of the scale type; cones have 4-6 scales; foliage is light green. Juniperus communis Common Juniper Leaves are awl shaped; cone is dark blue and berry-like.

  • Common Conifers in New Mexico Landscapes
    Ornamental Horticulture Common Conifers in New Mexico Landscapes Bob Cain, Extension Forest Entomologist One-Seed Juniper (Juniperus monosperma) Description: One-seed juniper grows 20-30 feet high and is multistemmed. Its leaves are scalelike with finely toothed margins. One-seed cones are 1/4-1/2 inch long berrylike structures with a reddish brown to bluish hue. The cones or “berries” mature in one year and occur only on female trees. Male trees produce Alligator Juniper (Juniperus deppeana) pollen and appear brown in the late winter and spring compared to female trees. Description: The alligator juniper can grow up to 65 feet tall, and may grow to 5 feet in diameter. It resembles the one-seed juniper with its 1/4-1/2 inch long, berrylike structures and typical juniper foliage. Its most distinguishing feature is its bark, which is divided into squares that resemble alligator skin. Other Characteristics: • Ranges throughout the semiarid regions of the southern two-thirds of New Mexico, southeastern and central Arizona, and south into Mexico. Other Characteristics: • An American Forestry Association Champion • Scattered distribution through the southern recently burned in Tonto National Forest, Arizona. Rockies (mostly Arizona and New Mexico) It was 29 feet 7 inches in circumference, 57 feet • Usually a bushy appearance tall, and had a 57-foot crown. • Likes semiarid, rocky slopes • If cut down, this juniper can sprout from the stump. Uses: Uses: • Birds use the berries of the one-seed juniper as a • Alligator juniper is valuable to wildlife, but has source of winter food, while wildlife browse its only localized commercial value.

  • Red Band Needle Blight of Pine
    231 Corstorphine Road Red Band Needle Edinburgh EH12 7AT www.forestry.gov.uk Blight of Pine INFORMATION NOTE BY ANNA BROWN, DAVID ROSE & JOAN WEBBER OF FOREST RESEARCH SEPTEMBER 2003 Forestry Commission SUMMARY ARCHIVE Red band needle blight is an economically important disease affecting a number of coniferous species, in particular pines. It has a world-wide distribution, and since the late 1990s the incidence of the disease in the UK has increased, particularly on Corsican pine (Pinus nigra var. laricio) in Thetford Forest Park. The disease causes premature needle defoliation, loss in yield and sometimes tree mortality. In other countries where the disease has a significant economic impact, successful methods of control have included good stand management, fungicide application and the use of resistant species. INTRODUCTION infected by D. pini. The majority of this information was obtained from Gadgil (1984) and Ivory (1967). Apart Red band needle blight, so called because of the symptoms from pines, other coniferous species such as European it causes on pine, is an economically important disease with larch (Larix decidua), Norway spruce (Picea abies), sitka a widespread distribution (Gibson, 1974; Bradshaw et al., spruce (Picea sitchensis) and Douglas fir (Pseudotsuga 1997). It is caused by the fungus Mycosphaerella pini, but menziesii) are occasionally susceptible. is probably better known by the name Dothistroma pini (formerly D. septospora). In total, over 60 pine species are reported to be prone to infection: radiata pine (Pinus radiata), Austrian pine The disease was first observed in the UK in 1954 on nursery (Pinus nigra) and ponderosa pine (Pinus ponderosa) are stock (Murray and Batko, 1962), but until recently it was considered to be the most susceptible, and spreading- only seen very sporadically.

  • Pinus Nigra Austriaca (Austrian Pine / Black Pine)
    Pinus nigra Austriaca Austrian Pine / Black Pine Pinus nigra Austriaca is one of the most popular plants sold at Deepdale Trees. Native to Austria and the Balkans and known as Austrian Pine or European Black Pine, this tough evergreen plant grows well in a wide range of conditions. It is ideal for screening and windbreaks and is tolerant of urban, coastal and exposed environments. When young it has a conical form and a strong growth rate. With age, the growth slows and the form of the tree broadens and becomes more irregular. Eventually it will reach approximately 25-30m in height. The stiff needles are arranged in pairs, longer and greener than Scots Pine and with a denser habit. When the new growth comes through in the spring it is in the form of bright green ‘candles’. As with all Pines, cones are produced, green initially and brown when fully matured 2-2.5 years later. The bark is grey and fissured, with silvery plates. When introduced to this country in the 18th Century, it was planted alongside other new and foreign species. Some of these still exist today and suitably demonstrate what a February 2014 wonderful specimen this can be. Pinus nigra Austriaca is available from Deepdale as a standard, Pinus nigra Austriaca 30-35cm girth in air-pot feathered or bonsai plant. Plant Profile Name: Pinus nigra Austriaca Common Name: Austrian Pine Family: Pinaceae Height: up to 30m Demands: Thrives in full sunlight. Tolerant of most soils and urban, coastal and exposed environments Foliage: Evergreen, long dark green needles in pairs Bark: Scaly bark with orange-red, flaking plates Fruit: Brown cones, 5-9cm in length Pinus nigra Austriaca 70-80cm girth in crate Deepdale Trees Ltd., Tithe Farm, Hatley Road, Potton, Sandy, Beds.

  • Tree Species Used in Historical Shipbuilding and Their Risk of Being Attacked by Teredinidae
    Tree species used in historical shipbuilding and their risk of being attacked by Teredinidae Johann Müller Abstract - This paper gives an idea of the range, biodiversity and mechanism of the bore-worm, whose fast work of destruction could especially be observed at an artificial shipwreck. Conclusions as for archaeology are drawn (see also summary at the end of the paper). Inhalt - Der Beitrag gibt einen Einblick in Verbreitung, Artenvielfalt und Wirkungsweise der Bohrmuschel, de- ren schnelles Zerstörungswerk besonders an einem künstlichen Wrack beobachtet werden konnte. Folgerungen für die Archäologie werden gezogen. Tree species used for boat- and shipbuilding In historical naval architecture and construction the tree species used (number of kinds unknown) varied, depending on availability and suitability. Usually the timber for ship- and boatbuilding was taken from regional forests nearby. Larger vessels for the high seas were generally built at places near the coast, using rivers for transporting the wood from inland areas to the coast. If the required kinds of wood were unavailable in their own homeland, the shipbuilders of the sea powers procured the timber from countries far away, usually transporting it by sea. The selective demand for special kinds of wood led to karst formation in entire regions as there was no controlled forestry taking care of replanting of trees. A typical example is the Lebanon Cedar (Cedrus libani ) whose wood was used as early 5 000 years ago. As a result of overcutting, the formerly numerous cedar stands one to two thousand meters high-up in the mountain regions of Lebanon vanished 1. Cedar timber from Lebanon was shipped particularly to Egypt 2.
